LAClNG-STUD-SETTING MACHINE.

SPECIFICATION" forming part of Letters Patent No. 565,810, dated August 11, 1896.

Application filed July 1894. Renewed November 4, 1895. Serial No 567,955. (No model.)

To all whom it may concern.-

Be it known that I, GEORGE A. SrILns, of Brookline, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Lacing- Stud-Setting Machines, of which the following is a specification.

This invention relates to machines for settin glacin g-studs in fabric, and is particularly directed toward providing improved means, carried by the plunger, for receiving the studs from the raceway and holding them while they are set in the fabric; improved means for transferring the studs from the raceway to this receiving and holding device, and,incidentally, a start-and-stop mechanism in combination with the means for actuating the said stud receiver and holder.

To the above ends the invention may be said to consist in the novel features of construction and combinations of parts recited in the appended claims and described in detail hereinafter.

The accompanying drawings, which form part of this specification, illustrate an embodiment of the invention.

Figure 1 represents a front elevation of the machine. Fig. 2 represents a side elevation of the machine. In both these views the stud receiver and holder is shown in position to receive a stud from the raceway. Fig. 3 represents-a side elevation with the stud receiver and holder in position over the anvil and ready to descend with the stud. Fig. 4: represents a side elevation of part of the machine, showing the plunger as having descended. Fig. 5 illustrates the movement of the stud-holder which disengages it from the stud after the same has been set in the fabric. Fig. 6 represents a perspective view of the stud-transferringdevices. resents a section on line 7 7 of Fig. 6. Fig, 8 represents a similar view with the parts under a different adjustment. Fig. 9 represents a section taken substantially on line 9 9 of Fig. 8.

In the drawings the letter a designates I the supporting-frame of the machine; I), the

main driving-shaft; c, the vertically-reciprocatin g plunger carrying a head o, groovedto Fig. 7 repreceive a crank-pin on a disk I), affixed to or formed on the driving-shaft, the form of said groove being such as to permit a dwell in the plungers operation at different points to allow for the stud-receivers movements hereinafter described. (See dotted-line representation in Fig. 1).

The letter (Z designates the hopper, which contains the supply of studs 2, and e the raceway or chute, which extends from said hopper to a point back of the plunger, the said chute being slotted in the rear side, so that the bifurcated shank of the studs may protrude therethrough, as shown, and also being provided with a flange for the neck-openings of the studs to embrace. The studs arrive at the lower open end of the raceway with the bifurcation of their shanks disposed vertically, as shown. A stud receiver and holder f is pivoted to the lower end of the plunger 0, as shown at f and is designed to swing on its pivot between the raceway and the anvil g. Said receiver is formed or provided with a flange f 2 at its outer end, designed to register with the flange of the raceway and occupy the neck-opening of the stud, which it receives from said raceway. A pin f? is fitted to a bore in the receiver opposite the flange f and is impelled toward said flange by a spring. (Indicated in dotted lines in Fig. 2.) This pin bears against the head of the stud on the flange f and its end is slightly beveled or rounded, so as to permit of the stud displacing it when transferred from the raceway.

The receiver f is moved on its pivot through the following means: A block h is affixed on the driving-shaft b and is formed with .a camgroove h, which receives a roller on a lever 7L pivoted intermediate of its ends to the frame of the machine and having its lower end connected by a rod h with the receiver The form of the cam-groove h is such as to swing the stud-receiver from its position shown in Fig. 2, where it receives the stud from the raceway, to its position shown in Fig. 3, where it holds the stud over the anvil;

also to cause it to remain in this latter posi- ,.tion while the plunger descends and sets the stud in the fabric; also to swing the studholder outward, as shown in Fig. 5, in order to disengage it from the stud and to swing the holder back to its receiving position.

The means here shown for transferring the studs from the raceway to the receiver are of the following construction and operation: A transfer-finger i is provided to engage the bifurcation of the stud, said finger being flattened, as shown, to facilitate such engagement, and this finger is caused to traverse a path of movement calculated to engage it with and disengage it from the studs and to move them laterally out of the raceway into the receiver. The finger i is fastened in a holder t" on a transversely-sliding carriage t fitted to a slideway in the under side of another carriage i movable forward and back in a slidewayi on the machine-frame. Rectangular openings t and t are made in the two carriages, respectively, and extend transversely to each other, partially registering, as shown. A vertical shaft j, connected with the driving-shaft by spiral gears j and 3' carries at its lower end a segmental cam j occupying the openings and i and broad enough to engage sides of both. It will be understood that by successive engagements of this cam with sides of the two openings a movement of the finger t' in a rectangular path will be produced. By the action of this segmental cam against the front side of the opening 1', Fig. 7, the finger is projected into the bifurcation of the studs shank. Then the cam acts against the inner side of the opening i Fig. 8, and moves the finger lat-v erally to take the stud out of the raceway and into the receiver. The cam next acts against the rear side of the opening 6 and retract-s the finger, disengaging it from the stud, and, continuing, moves the finger laterally back to its original position by action against the outer side of the opening 2'.

A friction-clutch it connects the shaft 1) with a driving-pulley b and a shipper-lever 7a, connected with said clutch, has ablock k at its lower end for engagement of alatch pivotally connected with the lever h and having an inwardly-projecting pin 70 for engagement of a pivoted and spring-held trigger k on the upper end of a slide 70, which is connected with a treadle. (Not shown.)

When the slide 7a is lowered, as in Fig. 1, the latch 70 rests on the block W, and the forward swing of the lower arm of the lever 7t ?-carries the lug at the end of the latch against the block 70 and consequent movement of the shipper-lever it releases the clutch and throws the machine out of operation. When this takes place, the pin 70 is over the trigger W, and the operator starts the machine by depressing a treadle, which raises the slide 70 and causes the square end'of the trigger to act against the pin 70 and raise the latch out of engagement with the shipper-lever, whereupon the clutch is closed by a suitable spring, and the machine starts. The slide 70 having been lowered again, the machine will be au tomaticaily.stopped at the completion of a cycle of its operation. If it is desired to have the machine work continuously, the slide 7c is held up with the trigger in the path of the pin 70 and the latters action thereagainst will raise the latch as its lug approaches the block 70 the spring-held trigger yielding, so that the engagement of the pin with its side edge will raise the latch.

A brief recitation of a cycle of the machines operation will sufiice, when taken in connection with the foregoing description.

WVith the stud-receiver in the position shown in Fig. 2, the transfer-finger enters into engagement with a stud and then moves laterally, carrying the stud into the receiver. The receiver now swings down to a vertical position over the anvil, as shown in Fig. 3, and dwells in that adjustment while the plunger descends and sets the stud. (See Fig. at.) After the stud has been set, the holder f swings outwardly, as shown in Fig. 5., to disengage it from the stud, and then swings back to its first position to receive the next stud. In the meantime the transfer-finger has receded and moved laterally, and advances into engagement with the next stud. This completes a cycle of the machines operation.

It is evident that the invention is not limited to the form of means here shown, which may be variously modified.

. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-
